First, the standard disclaimer: Past performance does not guarantee future results. That said, if Friday was any indication, we could have a great day with matching mole on 1/26.
When he said he would be visiting the Bay Area and was up for a day of birding with local Kossacks, I asked if he had a wish list of species he'd like to see. Based on his list, I think a trip to Solano County and the Delta is the best plan. For example, this is what we saw as soon as we turned onto Branscombe Road for the start of the "official" trip:
Adult Red-tailed Hawk (front pole) and Adult Ferruginous Hawk (rear pole).
How's that for a compare and contrast opportunity? Not bad, but if you really want to compare....
